So let’s all have a Black Celebration1. For the second year running, Elesar Ltd is allowing RISC OS users to benefit from Black Friday – a sales event from the Untidy States of Overpuddle2 that has started to catch on here in the UK. For Overpuddlians, the last Thursday in November is a national holiday [...]
Sadly, though, the time shift it has engaged isn’t some kind of time machine. The date has been published for the Recursion Computer Science Fair, 2018 – a multi-platform event with a focus on education that takes place at the King Edward VI School in Stratford-upon-Avon. Despite Recursion not being a RISC OS show, there [...]
Having visited the RISC OS User Group of London (ROUGOL) twice before, Dr Colin Wright will be the group’s guest speaker again on Monday, 20th November, 2017. Colin has visited the group before, in 2001 and in 2008, with the subject of both talks being RADAR – in particular, RISC OS-based RADAR systems. Those systems [...]
With a growing catalogue available from AMCOG Games, it should come as no surprise to anyone that there would eventually be some kind of compilation available – and that has been the case since this year’s Southwest Show, when the company began selling a CD featuring their first five games. The individual games continue to [...]
It’s meeting time in the Midlands this Saturday, 18th November! With this being the Midlands User Group‘s last meeting of this year, those in attendance will be reviewing what looks to have been an exciting year for the operating system, and looking forward to 2018; discussing topics people would like to see covered at meetings, [...]
A couple of years ago, RISC OS Open Ltd started building versions of RISC OS with “zero page relocation” – with the memory map changed such that the kernel’s workspace that started at the bottom of the addressable memory was moved to a higher location. This was an important step for security and stability, and [...]
First launched at the recent London Show, where it could be picked up on compact disc, Protector is the latest release from AMCOG Games, and it has now been updated to version 1.17, and for a mere £9.99 can now be purchased from !Store. The game is set on a world in which the planet [...]
Meanwhile, I have yet to get the final Wakefield Show video finished and uploaded! ROUGOL member Leo White, who records the theatre talks at the London Show, has now uploaded the recordings of this year’s talks to YouTube. In alphabetical order: BBC Media Preservation (Paul Emerton) CJE Micro’s (Chris Evans) MW Software (Martin Würthner) R-Comp [...]
The Southampton RISC OS User Group will be meeting again this coming Tuesday, 14th November, from 7:00pm until 9:00pm at: Itchen College Sports Centre, Deacon Road, Southampton. Anyone who uses or has an interest in RISC OS is welcome – there is no admission fee – and visitors are welcome to bring along any hardware [...]
The next meeting of the Bristol RISC OS Users group will take place on Wednesday, 8th November – but not at the usual venue. This month, the group can be found in a pub a short walk away from their normal meeting place. The meeting will be held at The Eldon House pub, which can [...]
Set your clocks for this year’s London Show at the St. Giles hotel, Feltham, on Saturday 28th October. The show is open to the public from 11am to 5pm, which also happens to be the last day of summer time in the UK.
Aha. I see. So PCI doesn’t want to claim pages it doesn’t need, but wants to lay claim to pages it hasn’t allocated for itself. Sounds like you need a PreAlloc flag, to inform whatever that while the page isn’t actually allocated, something has laid claim to it. Or, in your list, the earmarked option. ;-)
I’ve had a look in the RISC OS sources for the imx hdmi audio driver but not found it.. Those are in a private repository. I’m not sure what the timeline is for releasing them to the public repo – you’d have to check with R-Comp. I can’t remember exactly how I first got HDMI audio working for the iMX6, but one of the key things was to make sure the machine w […]
I must admit to having similar frustrations with my Mac and getting it to speak NFS/Samba. Gave up in the end! Back in the day, I used NFS a fair bit with RISC OS 3.6 to 4.0 talking to Linux and Windows (!) machines, so I know it’s possible.
sorry, spdif I mean. I’ve been trying to write some basic sound drivers on the iMX6 but so far have failed using HDMI and SPDIF. I attempted to port the imx6 sdk platform tests, but when attempting to write to the spdif tx, the system hangs and hdmi gives me silence. I configured the spdif tc as follows: HW_IOMUXC_SW_MUX_CTL_PAD_ENET_RX_DATA0_WR( BF_IOMUXC_S […]
Why does the PCI module need a specific contiguous block for its heap ? For direct hardware access to chunks of memory, I could understand, but for its heap? The heap is used to implement PCI_RAMAlloc, which is used by assorted drivers which want easy access to physically contiguous memory (and don’t have any constraints like e.g. needing to remap the memory […]
I might be stupid here but… Why does the PCI module need a specific contiguous block for its heap ? For direct hardware access to chunks of memory, I could understand, but for its heap? And… Surely if something else (video driver or whatever) also wanted specific physical pages, wouldn’t it be requesting different addresses (thus being allocated different pa […]
On startup the PCI module looks for a physically contiguous block of memory around 32MB in size for it to use as the PCI heap. Once it’s found the region, it remembers the base page number, and then requests appropriate page numbers from within that region on the DA PreGrow calls. This works fine, so long as there are no other components in the system which […]
Many many years ago I wrote an Internet module for Red Squirrel which passed across calls to the Windows network stack. It was a pretty horrible hack, but it worked for the limited amount of testing I did with it. Strangely enough just after I donated the source, something very similar appeared in Virtual Acorn. Would be great for RPCEmu IMHO.
I had a go at 32bitting the !OWW app years ago by patching to !RunImage – but no unit to test it on. (I seem to remember there was a set of ‘C’ source files) The hardware seems to be still made in Mexico. (Dallas Semiconductor 1-wire weather station)
